USB Power Devices

Here I am looking at two different devices to provide power, the first fits round your wrist like a bracelet to power your PDA or Phone. The second is a box to provide power to USBdevices when the mains are not around.

This is a black rubber bracelet weighting 81grams. It is 26cm long, 3.5cm wide a maximum of 1.3cm thick. It has six battery cells three either side of the seventh cell that is the charging indicator with four white LED’s and a push button which you press when you want to use some of its power. There is a micro USB socket on the side and all the supplied fifteen different heads either fit into that or a coiled 50cm extension unit.
